MEANS FOR SECURING WATCH-MOVEMENTS IN THEIR CASES.

SPECIFICATION forming part of Letters Patent No. 783,611, dated February28, 1905.

Application filed December 31,1903. Serial No. 137,272.

To all whom it 'lruty concern: tween the head of the bolt and thespacing Be it known that I, FeANgioIs OnEvILLA'r, a member. citizen ofSwitzerland, residing at Bienne, The movementis preferably provided withCanton of Berne, Switzerland, have invented one or more recesses cf inits periphery and 5 certain new and usefulImprovementsin Mean's adaptedto receive the spacing members 1 I), for Securing WVatch Movements inTheir which project slightly beyond the periphery Cases, of which thefollowing is a clear, full, of the movement. These spacing members I andexact description. should preferably [it the recess, whereby they Myinvention relates to an improven'ient in are held against side rocking,and so serve to [O the construction of watches, and more partichold thebolts against similar motion.

This is of a distinct advantage, because by it the straincomes directly upon the front plate and it is not so apt to be sprung aswould be the case if the screws were merely tapped into the lower partofthe movement and did not extend into the front plate.

It will be obvious that many changes may be made in the constructionshown without departing from the scope of my invention as claimed, and 1therefore do not limit myself to the particular construction describedand illustrated.
